Definitions

  • the invention primarily relates to a method of aiding the movement of work trains on a railway line under construction.
  • a track On a line in operation, a track is divided into sections of 400 to 2500 m, on each of which the trains move at a speed depending on a signal exhibited at the entrance to the section, usually the colour of a three-colour traffic light, which is green, if the section is free, orange, if the next section is occupied by a train—the light at the entrance of this next section is therefore red-, and red, if the preceding section is occupied.
  • the presence of a train on a section is detected by a track circuit which controls the signalling elements that have just been evoked.
  • the present application concerns primarily a method of aiding the movement of work trains on a railway line under construction with two tracks that are adjacent and two-way, managed from a central block PC by a PC chief in which
  • the technical effect of the method of the invention resides in the ability, in certain conditions, to have a work train move at the speed of the line, much greater than the speed of movement when running by sight and to gain precious time.
  • the invention can be used, on 10 to 15 km sectors, to achieve a speed of 80 km/h instead of 30 km/h in work, and to move at an average speed of 45-50 km/h when it is only 20-25 km/h with a running-by-sight movement.
  • each block delimiting a sector, extending over a certain length
  • a train leaving a set of formation sidings of a marshalling zone of a work base travels via a track junction block before moving on the line, an agent of the points-marshalling block, after agreement by the PC chief, controlling the predicted itinerary over the track junction block.
  • the agent of the points-marshalling block delivers the authorization for the train to leave the set of formation sidings to move on the line.
  • a signal is given to the work train that it has reached a beginning or an end of block Pi and
  • the invention also relates to a system of aiding the movement of work trains on a railway line under construction with two tracks that are adjacent and two-way managed from a central block PC by a PC chief, the tracks being divided into sectors Si extending between two end blocks Pi (i and i+2) on which the trains can move in section or in work mode, the system comprising
  • a sector Si is represented on the block diagram of the central block PC as totally occupied when a work train is moving on it.
  • the means of locating trains on the sectors comprise
  • the signalling elements are indicator panels but may also be, according to a more elaborate form of embodiment, radio beacons.
  • this transmission may be automatic.
  • FIG. 1 illustrates the general principle of work train movement in section according to the method of the invention
  • FIGS. 2 , 3 and 4 show an example of signalling elements equipping the railway lines for the location of the trains on the sectors, comprising respectively one one-way track, one two-way track and two two-way tracks;
  • FIG. 5 is a functional block diagram of the system of aiding the movement according to the invention.
  • FIG. 6 is a flowchart illustrating a typical example of message interchange, conforming with the invention, between the work trains and the central block;
  • FIG. 7 is a flowchart of the operation of the aid system according to the method of the invention.
  • FIG. 8 shows an example of the display of a block diagram panel of lines under construction and of the control of movement according to the method of the invention.
  • the tracks 100 ′ and 100 ′′ of the line 200 of a railway under construction connect at least one elementary work-site CE to its work base BT.
  • the work base BT is arranged so as to allow the constitution and distribution of work trains TTX A, B, etc on the line 200 with the elementary work-site CE as their destination.
  • a train leaving a set of formation sidings 196 of a marshalling zone 197 of a work base 198 travels via a track junction block 199 before moving on the line, an agent of the points-marshalling block 195 , after agreement by the PC chief 194 , controlling the predicted itinerary over the track junction block 199 .
  • a line 200 is divided into successive adjacent sectors Si, S i+2 , etc. on the track 100 ′ and S i+1 , S i+3 , etc. on the adjacent track 100 ′′.
  • Blocks P i , P i+2 , etc and P i+1 , P i+3 , etc. respectively delimit these sectors on these tracks.
  • the blocks P i , P i+2 , etc. have a length of track 120 , 140 , etc. of 1500 metres at least, whereas the sectors S i , S i+2 , etc. may have a length of track 130 , 150 , etc. much greater (approximately 10 km) so that they can run “in section”, at a speed of 80 km/hour approximately. In comparison, the blocks are always travelled by running by sight except when they are used as parking track.
  • These signalling elements may be radio beacons with frequencies locked onto the special channels recognized by equipment on board the trains, but here, the preference is more simply for indicator panels as described below.
  • system 400 of aiding movement comprises onboard electronic means available to the escort managers on the trains to help a PC chief situated in a central block PC to regulate and control the movement of the trains. These electronic means will be described later.
  • the lengths of track 120 , 140 , etc. of the blocks P i , P i+2 have ends which are at the same time beginnings of blocks for one direction of movement and ends of blocks for the opposite direction of movement.
  • additional signboards 123 , 124 indicate on which radio channel LR the work train TTX must communicate with the central block PC, the channels being different on these two signboards.
  • the radio channels used, or the sequence of numbers of blocks and of sectors travelled, constitute data for detecting the direction of movement of the trains.
  • the tracks are organized into blocks Pi and sectors Si on the track 100 ′ and into adjacent blocks P i+1 ( 220 , 240 ) and sectors S i+1 ( 230 , 250 ) on the adjacent track 100 ′′, and comprise indicator signboards disposed as previously ( 221 , 222 etc.— 122 , 121 etc. and 421 , 422 etc.— 322 , 321 etc.). Additional signboards indicate the track number V 1 OR V 2 . Finally, points 301 and 302 are disposed to connect and allow two-way working of the two adjacent tracks, bypassing the elementary work-sites if necessary and providing for trains moving in opposite directions on one and the same track to cross.
  • Each work train TTX 80 ( FIG. 5 ) comprises a radio transceiver 81 and, coupled to the latter, a man-machine interface (MMI) 82 , with a keyboard and screen not shown, and allowing the escort agent to send messages to a central block 90 and to receive messages, via the channel LR of a radio link therewith.
  • MMI man-machine interface
  • the central block 90 for its part comprises central means 91 of communication including a radio transceiver 92 and a modem 93 for converting the signals received in baseband assimilable by a computer 94 for regulating and controlling the movement of the trains.
  • the computer 94 comprises essentially means of managing and means of processing data in liaison with a block diagram panel 70 , here a video display screen, means 50 of storing the messages and means 60 of storing data, in particular for controlling the display of the block diagram panel in display data characteristic of the lines, the sectors, the blocks and the location of the work trains and of the elementary work-sites.
  • the computer 94 comprises means 95 of managing the messages received on the modem 93 , means 96 of processing the detection and location data contained in the messages received, and means 97 of managing the messages to be sent via the modem 93 . It is also connected to input means 98 , here a man-machine interface MMI comprising at least an alphanumeric keyboard and screen in particular for entering data for controlling the block diagram panel, including the display data, and storing them in the means 60 , or for making requests to display messages stored in the means 50 in the form of a log.
  • MMI man-machine interface MMI comprising at least an alphanumeric keyboard and screen in particular for entering data for controlling the block diagram panel, including the display data, and storing them in the means 60 , or for making requests to display messages stored in the means 50 in the form of a log.
  • the module 95 dates and stores the messages received in the means 50 and the module 97 for managing the messages to be sent generates dates and stores the messages sent in these same means 50 .
  • the module 96 for processing the detection and location data it is arranged so as to interpret the messages received, verify the movement conditions, deduce the tenor of the messages to be sent, and where necessary update the block diagram panel.
  • the train 80 may, during a step 1 , move and access a block Pi of the track 100 ′ of the line 200 by running by sight on the portion of track 120 of the block, from the beginning of the block indicated by the signboard 121 , to the end of the block, indicated by the signboard 122 .
  • the escort agent that is to say the train 80 , then, in step 2 , asks the PC chief, that is to say the central block 90 , for authorization to move on the length of track 130 of the sector Si by sending a radio message M 1 on the channel LR using his transceiver 81 .
  • the channel LR used previously indicated by a signboard 123 (or 124 ) is here specific to the direction of movement 101 (or 102 ).
  • the escort agent enters on the MMI 82 the data comprising the message M 1 , that is to say at least the identification A of the train and the number P identifying the block Pi reached, indicated on the signboard 121 for the beginning of the block (DP 21 ).
  • this message M 1 is received by the transceiver 92 of the PC 90 , is digitized and decoded by the modem 93 , then, during the subsequent step 4 , after storage in the means 50 and display on the MMI 98 by the module 95 , is analysed by the processing module 96 .
  • This analysis is carried out according to certain criteria, developed later, for deciding on the mode of movement over the length of the track 130 of the sector Si or on the stopping of the train on the length of track 120 of the block Pi.
  • step 5 a wait message M 2 is generated by the module 97 for managing the messages to be sent and, at the same time as being stored in the means 50 , is sent by the transceiver 92 to the transceiver 81 of the train A, for example, via the same channel LR.
  • the receipt by the escort agent of the message M 2 has the effect, in step 7 , of causing the train to stop at the end of block signboard 122 .
  • the module 97 for managing the messages to be sent in step 6 , generates a message M 3 authorizing the train A to move in section on the length of track 130 of the sector Si.
  • This message M 3 is also stored in the means 50 .
  • step 8 this message is transmitted to the train 1 by the transceiver 92 .
  • the escort agent in step 9 , sends an acknowledgement message M 4 to the PC chief and, in step 10 , the train A moves in section on the sector Si.
  • step 11 the acknowledgement message M 4 is managed by the management module 95 and the processing module 96 updates the block diagram panel 70 while storing, in the means 60 , the occupancy of the sector Si by the train A.
  • the log stored as has been seen in the memory 50 , may be viewed at any time on the screen and used for example at the request of the PC chief thanks to the MMI 98 , in correlation with the block diagram panel 70 which provides him with any aid he requires.
  • the transceiver 92 on receipt of a message Mi originating from the train 80 via the receiver 92 of the central block PC 90 , in a step 21 , the transceiver 92 transmits the message Mi to the modem 93 converting the analogue message received into a digital message that can be understood by the computer 94 in a manner known to those skilled in the art.
  • the module 95 for managing the messages received extracts from it the number P of the block Pi reached, the identification A of the train 80 , the nature of the request, for example a request to move on the sector Si following the block Pi in the direction of travel of the train indicated by the channel LR, and supplements these detection and location data A, P, LR, during a subsequent step 23 , with any additional data available in the memory 50 and entered by the PC chief using the MMI.
  • additional data may for example specify the composition of the train A, the specifics of the block Pi, the various radio channels used depending on the tracks and the direction of movement, the urgency of the routing of the train A, etc.
  • the detection and location data are transmitted to the processing module 96 which, during subsequent steps, searches in succession in the memory 60 for:
  • Each of the steps 25 , 26 , 27 then computes the numbers N 1 , N 2 , N 3 of sectors free of trains between the sector Si and the sectors Sj and Sk, or the location S 2 .
  • These numbers N 1 , N 2 , N 3 are compared with minima n 1 , n 2 , n 3 that must not be exceeded, during a step 28 , in order to decide according to whether the minimum concerned has or has not been exceeded, that:
  • the management module 95 updates the log in the storage means 50 and the block diagram panel 70 in the storage means 60 .
  • n 1 , n 2 , n 3 The minima n 1 , n 2 , n 3 not to be exceeded depend on the safety conditions established in advance.
  • a train B may not enter a sector Si already occupied by a train A running in the same direction:
  • a train B running in one direction may not enter a sector Si if a train A running in the opposite direction on the same track is occupying the sector S i+2 :
  • the block diagram panel displayed on the screen 70 may have the aspect shown in FIG. 8 .
  • three lines under construction, L 1 , L 2 , L 3 have been represented, each one comprising two tracks V 1 and V 2 , and on each track, the sectors Si, extending between the end or beginning blocks Pi depending on the direction of movement, i ⁇ 2, i, i+2, etc., and the adjacent sectors S i+1 between the blocks P i+1 .
  • Each line L 1 , L 2 , L 3 illustrates one of the three preceding cases of control exerted by the aid system 400 , that is to say:
  • a work train B On the line L 1 , track V 1 , a work train B is occupying the sector S 1 (i ⁇ 2) or the block P 1 i, occupation displayed on the panel 70 , and requests to move in section on the sector S 1 i.
  • the aid system 400 ascertains that it is preceded by a work train A occupying the sector S 1 j also displayed, j here being equal to i+2. If j ⁇ i is equal to or greater than n 1 , authorization may be given, since no train is moving in the sector Si.
